gsmsendsms sends SMS short messages using an GSM mobile phone.

       gsmsendsms attaches itself to the device given on the command line  (usually  an  GSM  modem)  using  the
       specified baudrate.  If no device is given, the device /dev/mobilephone is used. If no baudrate is given,
       a default baud rate of 38400 is used.

       gsmsendsms  accepts a phone number (recipient address) and the short message text as parameters. The text
       may have a maximum length of 160 characters which is the maximum SMS  message  length.  The  GSM  default
       alphabet is used for encoding. ASCII and Latin-1 characters that can not be encoded using the GSM default
       alphabet are converted to the GSM delta character (GSM code 16).

       Error  messages  are  printed to the standard error output.  If the program terminates on error the error
       code 1 is returned.

       The following two invocations of gsmsendsms each send the same SMS message to the number "1234":

       gsmsendsms -d /dev/ttyS2 -b 19200  1234 "This is a test."
       echo "This is a test." | gsmsendsms -d /dev/ttyS2 -b 19200  1234

/dev/mobilephone
                     Default mobile phone device.

-bbaudrate, --baudratebaudrate
              The baud rate to use.

       -cconcatenatedID, --concatenateconcatenatedID
              If an ID is given, large SMSs are split into several, concatenated SMSs. All SMSs have the same ID
              and are numbered consecutively so that the receiving phone can assemble them in the correct order.
              IDs must be in the range 0..255. Not all receiving phones  will  support  concatenated  SMSs  (and
              display  them as separate SMSs), since all the numbering and ID information is carried in the user
              data header element at the beginning of the SMS user data. This information may show up as garbage
              in such phones.

       -Cservicecentreaddress, --scaservicecentreaddress
              Sets the service centre address to use for all SUBMIT SMSs (may not work with some phones).

       -ddevice, --devicedevice
              The device to which the GSM modem is connected. The default is /dev/mobilephone.

       -h, --help
              Prints an option summary.

       -Iinitstring, --initinitstring
              Initialization string to send to the TA (default: "E0"). Note that  the  sequence  "ATZ"  is  sent
              first.

       -r, --requeststat
              Request status reports for sent SMS.

       -t, --test
              If  this  option  is  given the text is converted to the GSM default alphabet and back to Latin-1.
              This option can be used to find out how ASCII or Latin-1 texts are converted to  the  GSM  default
              alphabet.  Characters  that can not be converted to the GSM default alphabet are reported as ASCII
              code 172 (Latin-1 boolean "not") after this  double  conversion.  No  SMS  messages  are  sent,  a
              connection to a mobile phone is not established.

       -v, --version
              Prints the program version.

       -X, --xonxoff
              Uses software handshaking (XON/XOFF) for accessing the device.
